Second Post Publishes to Sidebar

Hi,

My blog can be found at marsiam.themooches.com

The second post is publishing to the sidebar, then throwing off the alignment of the rest of the page. It appears this way in firefox and in safari.

I tried changing the dimensions of images, and unpublishing entries, but regardless of what I do, the second entry winds up in the sidebar and ruins the rest of the page.

The individual post pages are fine, but I can’t figure out what the problem is. I haven’t made any changes to my blog recently as far as adding widgets or code, just writing a couple of new text only entries, so I am really confused as to why this happens.

Please assist.

Marisa
